Nelson Mandela's condition remained critical for the second straight night.

CNN is reporting crowds of people - and media - stood outside the hospital where Mandela is being treated.

Mandela's daughter Makaziwe Mandela left the hospital Monday night, reports CNN, citing the South African Press Association. Other family members, including ex-wife Winnie Madikizela-Mandela and daughters Zindzi Mandela-Motlhajwa and Zenani Mandela-Dlamini, left earlier in the day.

Mandela has been hospitalized since June 8 for a recurring lung infection.

Authorities had described his condition as serious but stable, but over the weekend, his health took a turn for the worse.

"The doctors are doing everything possible to ensure his well-being and comfort," President Jacob Zuma told the nation Monday.

The Associated Press reports Zuma, who called Mandela the "father of democracy" refused to give details of Mandela's condition, saying: "I'm not a doctor."

President Barack Obama, who arrives in Africa this week, is scheduled to visit Senegal, South Africa and Tanzania.
